What is the average cost of a barn conversion? (updated for 2024)

In 2024, unfortunately Covid price rises have not reversed. The impact of Brexit and Ukraine is still affecting material and labour costs.  We are finding that the cost to convert a barn is around £3,000/m2 (calculated using internal floor area including the first floor). After this, it depends a lot on personal taste, individual barn characteristics and complexities and of course local builder competitiveness.

Do barn conversions need planning permission?

In general, we find this the best route as it gives you more flexibility and longer to complete the build. See more about this on our blog here. Achieving permission via prior approval (permitted development) requires you to complete the build within three years, which can be restrictive.

Is a barn conversion cheaper than a new build?

Not really. Although a barn has an existing shell to use, there are additional complexities such as potential underpinning, additional structure required to support roof loads. Cows didn’t need an upstairs, so headroom restricts layout options.

How do you prepare for any challenges?

I would suggest working with someone familiar with barn conversions. Barns have unique planning stipulations and  limitations. A pre-application with the council is always a good idea. A structural survey including trial pits to establish existing foundation depths (if any) will help to ascertain costs.

How do you harmonise the old and the new?

It’s important to respect the agricultural history of a barn and not make it look too domestic. This means no dormers, porches or perpendicular extensions (something we are often asked about).

There are two types of barn: –

Modern steel-framed barns with concrete and timber cladding and

Traditional barns with stone, brick or timber walls.

We have turned all types into dwellings in the past.
